The 2021 Ig Nobel Chemistry Prize is awarded to a team of researchers (Jörg Wicker, Nicolas Krauter, Bettina Derstroff, Christof Stönner, Efstratios Bourtsoukidis, Achim Edtbauer, Jochen Wulf, Thomas Klüpfel, Stefan Kramer, and Jonathan Williams) for chemically analyzing the air inside movie theatres, to test whether the odors produced by an audience reliably indicate the levels of violence, sex, antisocial behavior, drug use, and bad language in the movie the audience is watching.
How are movies for the public audiences are rated? There are obvious reasons: to protect the children from unnecessary exposure to violence and sexual content. There are different approaches in various countries. Germany uses 0, 6, 12, 16, 18, while the United States has G (general audiences), PG (parental guidance suggested), PG-13 (Parents strongly cautioned), R (restricted), and NC-17 (no one 17 and under admitted). India the world´s most prolific filmmaker, uses U (0 to 11), UA (to 17), and A for adults.
Classification of movies is mostly a complicated affair and is guided by numerous parameters like the presence of sexual content, degree of violence, bad language. Also, these parameters are subjective and contentious issues because measuring parameters keep changing as the guidelines evolve with time.
In order to trim the subjective issue in measuring the presence of sexual content, degree of violence, bad language in movies, the study is carried out to estimate the content of same using chemically analyzing the air inside movie theatres, to test whether the odors produced by an audience reliably indicate the levels of violence, sex, antisocial behavior, drug use, and bad language in the movie the audience is watching. The study studied the presence of volatile organic compounds (VOC) and CO2 in cinema air.
The 2021 Ig Nobel Prizes were awarded at the 31st First Annual Ig Nobel Prize ceremony, on Thursday, September 9, 2021. The event honours the achievements that make people laugh, then think. The prizes are intended to celebrate the unusual, honour the imaginative — and spur people’s interest in science, medicine, and technology.
Most of the new winners will give free public talks to explain if they can, what they did and why they did it. These talks, the Ig Informal Lectures, will be presented one at a time, over the coming weeks. Because of the Covid-19 pandemic, this year’s lectures will be presented online, here at www.improbable.com, rather than in a lecture hall in their usual home, MIT (the Massachusetts Institute of Technology).
